CaO-Resisting Binders for Steel Waste Briquetting

Jianjie’s CaO-resisting binder is specially engineered for briquetting byproducts of steel, including lime-rich steel dust, mill scale, steel slag, and sludge. Its unique formulation resists CaO interference during cold-pressing, ensuring strong, stable briquettes even when raw materials contain high levels of free lime or complex mineral phases.

This binder enhances particle bonding, reduces cracking and expansion, and improves overall briquette durability during handling, storage, and furnace use. By enabling efficient recycling of CaO-containing steel waste, Jianjie’s solution helps steel plants lower disposal costs and maximize the value of their byproducts in a cleaner, more sustainable process.
